CERN is extremely welcoming about the arrival of Chen Zhou and Friedman.

So, when Cross arrived here before, he easily communicated about the related matters.

Now it's the turn of the main owner Chen Zhou and Friedman to be there, so CERN naturally took enough attention.

They arranged a special person to receive Chen Zhou and his group, and based on Cross's communication situation, two small seminars will be held to conduct academic exchanges.

Chen Zhou looked at the middle-aged man in front of him, and the middle-aged man in front of him was also looking at Chen Zhou.

However, Chen Zhou looked at the other party and was guessing who this person was.

The other party's eyes looked at Chen Zhou, but they seemed a little hot.

It is obvious that the middle-aged man had different ideas about Chen Zhou.

"Professor Johnstone, I'll bother you in this academic exchange."

Friedman's voice pulled back the look that Mitchell Johnstone had already been trapped in Chen Zhou.

Others may like to see beauties, but Mitch Johnstone likes to see genius physicists.

And Chen Zhou obviously belongs to this list.

"Professor Friedman, it is a good thing for you to come to CERN. How can you say it's troublesome?" Mitch Johnstone said with a smile.

Friedman said without comment, "Then let's hurry up and go to the linear accelerator lab."

Mitch Johnstone nodded slightly: "Okay, let's take you to visit the laboratory first, and let's have a good exchange afterwards."

Intentionally or unintentionally, Mitch Johnstone looked at Chen Zhou again when she said this.

Although Chen Zhou noticed it, he didn't care much.

The group followed Mitch Johnstone and headed towards CERN's two linear accelerator laboratories.

This is CERN's most basic accelerator laboratory and the longest-used laboratory.

The prototype concept of linear accelerator was first proposed by British scientist Professor Issin in 1924.

In an article titled "Principles of Methods for Generating High Voltage Pole Tunnel Radiation", he proposed the design pattern of a linear accelerator.

However, due to the limitations of the level of electromagnetic technology at that time, linear accelerators were not realized.

It was not until four years later that German scientist Rovvedro completed the world's first linear accelerator.

It was also from this that the physics community entered the era of accelerator experiments.

Many theories and predictions of high-energy physics can be verified in accelerator experiments.

In fact, it has only been a hundred years since the birth of the accelerator.

But its rapid development does prove the rapid progress of science.

Moreover, with the development of linear accelerators, they have also been applied to all walks of life.

Especially with medicine, the application of linear accelerators in medicine provides new treatment methods for tumor treatment.

"This is the Linac2 linear accelerator, which may be a little different from the linear accelerator you have seen before..."

Mitch Johnstone pointed at the accelerator device in front of everyone and began to introduce.

At the beginning of construction, CERN had a linear accelerator called Linac1.

However, later, because of the long service time, the maintenance cost was high and the maintenance value was not high, it was dismantled.

This is actually the same as SLAC shutting down the collider laboratory.

On the road of scientific development and exploration, there is also a law of survival of the fittest.

This rule applies not only to people, but also to research equipment.

"The accelerator is mainly composed of three high columns made of insulating material, and the accelerator tube in between them..."

"The accelerator is kept vacuum by a vacuum pump, and its appearance is streamlined, which prevents accidental discharge from any edges or protrusions..."

"There are metal rings in the accelerator tube. The way they are connected to the high-voltage generator can gradually increase the negative pressure of a series of metal rings from the bottom to the top..."

"The ion source that produces protons is installed at the upper end of the accelerator tube..."

"The positively charged protons are attracted by the negatively charged metal circle and shot down the pipe. At the same time, the negative voltage of the metal circle below continues to increase, and the speed of the protons continues to increase..."

"Below the floor at the ground end of the accelerator tube, there is a small chamber with a receiver, where protons can collide with matter, and in this process, bombardment can cause the transformation of the nucleus..."

Mitch Johnstone introduced the Linac2 linear accelerator extremely seriously.

He felt that he had never been so serious, nor had he introduced it from shallow to deep.

Thinking of this, Mitch Johnstone's eyes couldn't help but float to Chen Zhou.

Chen Zhou noticed it and also glanced at Mitch Johnstone.

Mitch Johnstone seemed to feel that he looked at Chen Zhou from time to time, and was a little impolite, so he immediately withdrew his gaze.

This made Chen Zhou even more and more strange.

He didn't understand what Professor Mitchell Johnstone always looked at him?

Do you think you are too handsome?

Although Chen Zhou himself also feels that he is becoming more and more handsome and charming, are you an uncle?!

Following the principle of the accelerator, Mitch Johnstone introduced some of the main features of linear accelerators.

In fact, linear accelerators can be designed, manufactured and debugged from front to back due to the convenient injection and extraction of beam current, strong beam current, high transmission efficiency, and good beam quality.

Therefore, compared with other high-energy accelerators, linear accelerators can have better practical applications.

At the same time, since the linear accelerator does not have the synchronous radiation limitation of the deflection beam, the electron beam can be accelerated to very high energy and other characteristics.

Linear accelerators are the only candidate for the next generation of ultra-high energy colliders.

Chen Zhou didn’t know if CERN had research on this aspect, but most of them couldn’t escape.

If you can have some contact or "communicate"?

Chen Zhou thought this would be a very good experience.

Thinking of this, Chen Zhou looked at Professor Mitch Johnstone for two more eyes.

"Well, Dr. Chen, there is something, please tell me the truth, is that OK?"

After the Linac2 linear accelerator visit, on the way to the area where the Linac3 linear accelerator was located, Cross quietly approached Chen Zhou, "draged" Chen Zhou away from the main force, and then asked in a low voice.

Chen Zhou glanced at Cross strangely: "What's the matter?"

Cross looked around and whispered: "That's right, why are you here for CERN?"

Chen Zhou was slightly stunned and did not understand Cross's meaning at the first time.

He said in surprise: "I followed Professor Friedman to have academic exchanges. What's wrong?"

Cross glanced at Chen Zhou, then looked around carefully, and then asked bluntly: "I mean, will you stay at CERN?"

Chen Zhou suddenly realized that this was the case.

He also suddenly understood why Professor Mitchell Johnstone would look at himself from time to time.

After thinking about it, Chen Zhou said softly: "I will stay for the time being, for academic exchange..."

After saying that, Chen Zhou didn't explain much and caught up with Friedman and others.

Cross, who was still there, was stunned for three seconds, and then a smile appeared on his face.

He understood what Chen Zhou meant.

One morning, it’s not long or short.

But Chen Zhou and Friedman and their party only visited the two linear accelerators laboratories, Linac2 and Linac3.

When I was having dinner at CERN at noon, Mitch Johnstone was no longer polite and took the initiative to come over.

"Professor Friedman, Dr. Chen Zhou, don't you know what you feel after watching it in the morning?"

Hearing Mitch Johnstone's words, Chen Zhou and Friedman looked at each other, and both of them smiled at the same time.

Friedman said: "Professor Johnstone, to be honest, I envy you a little! As the world's largest particle physics laboratory, your configuration is indeed the most complete. This, no matter the personnel,

It's the same with equipment."

Mitch Johnstone chuckled softly: "Professor Friedman, whether it was before or now, I believe that all the researchers at CERN are welcome to you."

Friedman shook his head and said with a smile: "No, I'm old and my mind is no longer jumping."

Mitch Johnstone didn't say much, but instead asked Chen Zhou again: "Dr. Chen Zhou, how do you feel after watching it in the morning?"

Chen Zhou thought for a while and said, "I don't know much about CERN. If we talk about these two linear accelerators alone, I think as a basic accelerator equipment, the performance and experimental nature of these two accelerators are quite good.

Not bad.”

"In addition, for the linear accelerator category, I don't know what the experimental plan of CERN is like, and whether it is ready for the ultra-high energy collider..."

Chen Zhou said it very directly. He was thinking, anyway, if you ask, then I naturally don’t need to be polite.

When Mitch Johnstone heard this, she was slightly stunned and then chuckled softly: "In about two days, CERN will start the next round of experiment planning. The content of the experiment also includes the rubber ball you just discovered."
